摘要

In our research, the effects of rare-earth element erbium (Er) on microstructures andrnmechanical properties of some aluminum alloys are investigated. It is shown thatrnaluminum alloys with Er additions, including Al-Mg, Al-Zn-Mg, Al-Zn-Mg-Cu, 1420 Al-Lirnalloys and high purity aluminum, have refined grain size, superior thermal stability, andrnhigher hardness or tensile strength with unchanged ductility. It is concluded that, in mostrnaluminum alloys, Er is an effective alloying element.
